中文摘要:
      以委内瑞拉超重油和新疆风城超重油为研究对象,进行了超声辅助降粘的研究.在实验中,制备了两类四种实验样品:分别掺入20%和30%柴油的两种委内瑞拉超重油样品、在O/W降粘体系下制备的委内瑞拉超重油样品和风城超重油样品.使用频率为18 kHz的超声变幅杆和24 kHz的超声清洗槽对上述四种实验样品进行超声处理,结果表明:1) 对掺入20%和30%柴油的委内瑞拉超重油,经过超声处理的超重油样品在20 ℃时粘度分别增高了25%和15%以上;2) 在O/W降粘体系超重油降粘中,风城超重油样品经过超声作用后,在20 ℃粘度降低了25%以上,而降粘剂的使用量可减少20%,超声辅助降粘效果明显;3) 在O/W降粘体系超重油降粘中,委内瑞拉超重油样品经过超声处理后,在14 ℃时,超声处理过的样品的粘度降低不高于25%,在高于这一温度的情况下则未观察到明显的粘度降低.文中对上述实验结果产生的原因进行了定性的分析.
英文摘要:
      In this paper, the effects of ultrasonic wave on viscosity reduction for Venezuela and Fengcheng ultra heavy oil are studied. Four types of ultra heavy oil examples are prepared for experiments: 80% Venezuela ultra heavy oil with 20% 0#diesel (Example I), 70% Venezuela ultra heavy oil with 30% 0#diesel (Example II), the oil-in-water (O/W) for Venezuela and Fengcheng ultra heavy oil (Examples III and IV) by using active macromolecule viscosity reducer. In the experiments, these four types of examples are irradiated by ultrasonic horn (18 kHz) and ultrasonic bath (24 kHz) respectively. Here are the results: (1) the viscosity of Example I irradiated by ultrasonic wave is 25% higher than that un-irradiated at 20 ℃, for Example II, 15% higher. (2) the obvious effects of ultrasonic wave on reducing viscosity can be observed for Example III whose viscosity irradiated by ultrasonic wave is 25% lower than that un-irradiated at 20 ℃ and 20% less quantity of active macromolecule viscosity reducer is needed. (3) For Example IV, no obvious effects are observed except at 14 ℃, where less than 25% viscosity reduction is observed for that irradiated by ultrasonic wave. The reason of the phenomenon observed in this paper is analyzed qualitatively.
